The Embedded Firmware Engineer is responsible for designing, developing, and testing firmware for advanced embedded systems used in high-power conversion and control applications. This role involves working with microcontrollers and SoCs (STM32H747, Texas Instruments J721E), implementing real-time operating systems (RTOS), and developing communication protocols (TCP/IP, Modbus, SPI, I2C, RS485, CAN).
The engineer will integrate control engineering techniques such as PID controllers, collaborate on system-level software in Python, and contribute to simulation and testing using Typhoon HIL. A strong understanding of electronics, power systems (e.g., inverters, battery management), and safe practices in high-power environments is essential. The role also includes developing PC-based test tools and participating actively in team meetings and agile workflows.
Attention to Detail: Ensures accuracy in contract documentation and proposal submissions.
- Implement communication interfaces and protocols: Ethernet (TCP/IP, Modbus TCP), SPI, I2C, RS485 (Modbus RTU), CAN bus.
- Apply electronics knowledge and use test equipment to support embedded development.
- Work safely in high-power test environments (on-site and off-site).
- Control Systems Engineers – Coordinate on implementing control algorithms (e.g., PID) and integrating them into embedded systems.
- Bare-metal and RTOS (MBED, FreeRTOS) development.
- Develop PC-based test tools using C# and Python.
- Integrate control engineering techniques such as PID controllers for power control.
- Hardware Engineers – Collaborate closely to integrate firmware with electronic hardware and troubleshoot hardware-related issues.
- Develop embedded firmware in C and C++.
- Use Typhoon HIL for model-based development and Hardware-in-the-Loop testing.
- Work with bare-metal and RTOS environments (MBED RTOS, FreeRTOS).
- Software Engineers – Work together on system-level software, PC-based tools, and embedded Linux components.
- Test Engineers – Partner to develop and execute test plans, especially for high-power systems and HIL simulations.
- Participate in team meetings and daily stand-ups, contributing technical insights.
- Project Managers – Provide technical updates, contribute to planning, and ensure alignment with project timelines.
- Contribute to system-level software development in Python.
- Document code and development processes.
